DECK FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. ,1 dated March 1902-Application filed June 8,1901.

T0 aZZ whom it may concern.-

Be it known that I, ISAAC TROLLEY, a subject of the King of GreatBritain, residing in Grantham, county of Lincoln, England, have inventedcertain new and useful Improvements in Decks for Grain-Binders, of whichthe following is a specification.

My invention is concerned more especially with that portion of the deckwhich is adjacent to the canvas rollers, and is designed to produce adeck in which it is impossible for the grain to collect and clog betweenthe deckroller and the deck; and to this end it consists in theemployment of an auxiliary deckroller, as will be hereinafter fullydescribed.

Referring to the accompanying sheet of drawings, in which the samereference characters are used to designate identical parts in all thefigures, Figure 1 is a perspective View of so much of the deck and itsassociated mechanism as is necessary to disclose my invention; and Fig.2 is a sectional view, on an enlarged scale, on the line A A of Fig. 1.

3 is the customary deck, having the needleslot 4 therein extending up tothe deck-roller 5, which is of the customary construction and which isjournaled in the side pieces 6 and 7 and is connected by the train ofgearing 8 with the top roller 9 of the lower canvas 10, so that it willrotate in the same direction as the canvas. The top roller 11 of theupper canvas 12 is of the customary construction. With this customaryconstruction which has hitherto been employed it frequently happenedthat stalks of grain would fall between the deck-roller 5 and the upperedge of the deck 3, and the heads being too large to pass through thecrevice would project upward in the path of the grain, being dischargedover the deck-roller 5, and this interferes seriously with the opera-Serial No. 63,693, (No model.)

tion of the machine. This difficulty occurs at the right-hand end of thedeck only, and to remedy it I journal the auxiliary deckroller 13 insuitable bearings formed on the deck 3 and in the side piece 7. Theresult of the employment of this auxiliary deckroller is that in case asuflicient quantity of grain should pass between the main deckroller 5and the auxiliary deck-roller 13 to clog up and interfere with the feedof the straw over them the wedging of the grain and the forced rotationof the deck-roller 5 will cause the auxiliary deck-roller 13, which isnormally stationary or possibly rotating in the'opposite direction, torotate in the direc tion indicated by the arrow in Fig. 2, in which casethe grain will be fed between the rollers 5 and 13 and the clogging thusobviated.

Having described my invention, what I claim as new, and desire tosecureby Letters Patent of the United States, is

1. In a device of the class described, the combination with the deck, ofthe lower can vas, and the deck-roller 13 looselyjournaled between theedge of the deck and the canvas, substantially as and for the purposedescribed.

2. In a device of the class described, the combination with the toproller, of the lower canvas, the canvas on said roller, of thedeckroller 5, gearing between the top roller and the deck-roller, thedeck, and the auxiliary deckroller 13 mounted between the deck and theroller 5; substantially as described.

In witness whereof I have hereunto set my hand this 11th day of April,1901.

ISAAC TROLLEY.
